What you might try is having a dummy sprite in the highest channel (48 was
it?). Then when you click on, say sprite 5, you swap the higher sprite's
cast member with sprite 5's cast member AND swap sprite 5's cast member
with the dummy cast member. Then have sprite 48 follow the mouseLoc. The
dummy member could be a single or zero pixel bitmap.
It's been several years since I used D5, so the following code will very
likely have some syntax problems. You may even have to substitute 'member'
with 'cast' as I don't recall when 'member' became the norm. Oddly enough I
can't even test this. the clickOn seems to return a 0 in D7.02. Perhaps it
should be replaced with the rollover(). Here's the gist of it, though:
on mouseDown
set clickedSprite = the clickOn
set theMem = the member of sprite clickedSprite
set the member of sprite 48 = theMem
set the member of sprite clickedSprite = "dummy"
repeat while the stillDown
set the loc of sprite 48 to the mouseLoc
updateStage
end repeat
set the loc of sprite clickedSprite = the mouseLoc
set the member of sprite 48 = member "dummy"
set the member of sprite clickedSprite = theMem
end
Note that any other animations that may be going on will pause while the
user is dragging the sprite around (due to the tight repeat loop). I'm sure
there are ways to get around that if you need to, but my D5 memories have
faded quite a bit & I don't recall which commands & features were available
back then. For instance, I don't think behaviors were available yet, were they?
Perhaps it could all be handled in the frame script? Set a flag on
mouseDown that the frame script detects and causes sprite 48 follow the mouse?
